Desire S problem - a way around?
I have all the problems with my Desire S that are reported here, since the update. My phone also kept freezing. To cut a long story short, I did the factory re-set then had the phone "repaired" by O2. The connection problem still remains.
But I have found a way to temporarily fix this without switching the phone off: If I disable the internet connection from the settings menu, then dial my own number (guess what? I get engaged tone!), I can then re-enable the internet connection and it all works again - until the next time.
I rue the day I installed the update and have advised others not to do so. I also have an open ref. with HTC on this - they have advised me to do a SIM swap, but I guess from reading this thread that it won't make any difference...
